so easy an idiot can do it
I bought this unit to fit on to the existing base and was worried that it would not connect to the other two alarms.
NO NEED TO WORRY it was so easy popped it on it worked less than 30 seconds

Good service and helpful support via the phone.
The alarm wasn't shipped with the required base plate and I had to speak to your customer help line staff to get one delivered. They were very helpful and quickly got a base plate posted to me, but nonetheless it was somewhat annoying that this omission happened.

Fitted well but one has given erroneous alarms,okay now.
On one occassion one of the alarms would not stop giving erroneous alarms, so we took it out for 24hrs. Replaced it back on the base and now seems okay.

Excellent product and couldn't have been simpler to fit. Bought it to replace the ionisation version as it was reacting to cooking smells just outside the kitchen. So far seems to have done the trick. Manufacturer could make it clearer which easichange units work with which base units but the safelincs chatline was excellent in advising me.

As easy to fit as the name implies: simply locate the lugs in the back plate and slide into place: 10 seconds flat
